Computing the Density of a Solid from Unit Cell Information
Example 13.9. Magnesium Oxide has a face-centered unit cell of
oxide ions with magnesium ions in the octahedral holes. The radius of the Mg2+ ion is 86 pm, and the radius of O2- is 126 pm. Calculate the densigy of MgO in grams per cubic centimeter.
Compute the volume of the MgO unit cell
Compute the mass of the MgO unit cell
Computer the density -- mass/volume
